What I need is the following: log all the states of the program counter and the rombank number, so that I can use the addresses to differ between what are variables/instructions/tilemaps/graphics, etc.
I was going to use some very crazy hack (ptrace in linux) to do such a thing. But if I use the source code of mgba this could be much easier and less time consuming.
Where in the source code I can find the routines that modify/read the pc(program counter) and rombank number?

I've tried savegamePath=sd:/mGBA/saves/, then savegameDirectory, then =/mGBA/saves/, a bunch of stuff to no avail. Either it doesn't work, or I've been calling it the wrong thing all this time.

I just downloaded gba for the first time on my window 7 laptop. I downloaded 7zip and winrar shortly after. Not sure if doing it in that order had something to do with the upside screen and flickering that keeps happening. How can I fix this? I attached an image below of what I keep seeing.

Amazing emulator so far, I wanted to know if there is an option or a command line option that can set the fullscreen resolution, currently it switch to your desktop which if you are at a too high resolution it is a killer in combination with the enhancement shaders...

I downloaded the file, and got a mGBA-0.6.1-osx.tar.xz and a mGBA-0.6.1-osx.tar.xz.cpgz and have no clue what to do with it.
I am trying to play Pokemon fire red. (Dont know if that matters)

Hey. I've come across a couple of games with issues in mGBA.

The first is Penny Racers (E) AKA Gadget Racers (U) or Choro Q Advance (J)

This game runs fine but the main player car sprite is all glitched up. It's the same in all 3 versions.

The other game is Rampage Puzzle Attack.

The game loads fine but the sound is borked. Nothing but screeches and whines. In the RetroArch build there is no sound at all.

These bugs occur in the latest dev build, 0.6.1 and the RetroArch version.

I hope it's okay to post the bugs here - I didn't see a general bugs thread. But I am old and blind so might've missed it!

i came to this forum as i discovered mgba may possibly be what i seek, although like other emulators/ programs it may not be but its worth asking as it seems interesting even if not possible for my purpose.

i have something specific i wish to do which requires me to connect a real gba to mgba (on a wii), use cheat codes on something, and send it back to the real gba.

more elaboratly, i wish to use mgba with a real gba (with and without sonic advance games) and the two sonic adventure gamecube games for the purpose of moving/ getting special chao pets with codes/ or through raising them on the chao garden in the gba games. if that makes sense.

i wish to know if this is possible, so far no emulators/programs have this ability (plus gbas tend not to connect to pc emulators, and wii based ones are not well used any more), i have a working gamecube capable wii, a real gba, and the gnc-gba cable but as i dont have the sonic advance games, nor a cheat device for gba any longer, it is far harder for me to work with and having the ability to transfer chao through the gcn to my real gba and then to the mgba for temporary purposes, and then back again would be very helpful but i dont know if this is possible or if it could be set up by someone somehow.

Hey. When I load F-Zero GPL (it also happens in quite a few other games) in the stand alone build of mGBA (latest release) the game has glitchy graphics on the menu screens. It takes the form of vertical black stripes across the screen. I'm not using any shaders. The emu is also set to its default OpenGL though the issue still happens when using the older OGL implementation. Software runs at about 1 fps!

When I run the mGBA build that comes with Retro Arch, all is well.

I'm on Windows 10 Pro with Intel 4600 onboard GPU.

Sorry if I'm not giving enough info. Please let me know if you need anything else.

Hiya. Is it possible to use cheat files on the Wii port of mGBA? If so, what format should they be in, where do I put them on my SD card and how do I use them in-game?

In particular, I'd like to use the AR codes like the ones that come along with Retro Arch to activate all vehicles in F-Zero: Maximum Velocity.

Thanks for any advice.

I could acess the menu to manage my save states and change controls, now for some reason i can't acess it, i tried pressing every button but nothing worked. I deleted mgba and installed it again but the problem persists.
